I don't mind some of the healthier frozen meals when I am depressed.
I also cook often with my crock pot/ slow cooker. I can put the ingredients in the pot in the morning and dinner is ready at dinner time. I've recently done a thread on this. A few people have shared recipes. (If you would like to view those, scroll down to the category named "distractions." You will see "recipes." under that, you will see "Favorite Crock Pot Recipes.") There are thousands of recipes online.
When I am feeling better, I cook and freeze batches so I have something made for meals when too depressed to cook.
just a couple of ideas for you.
